If any of the listed modules are not loaded yet, base silently attempts to require them (and silently continues if the require failed). Whether to require a base class module is determined by the absence of a global variable $VERSION in the base package. If $VERSION is not detected even after loading it, <base> will define $VERSION in the base package, setting it to the string -1, set by base.pm.

Will also initialize the fields if one of the base classes has it. Multiple inheritence of fields is NOT supported, if two or more base classes each have inheritable fields the 'base' pragma will croak. See fields, public and protected for a description of this feature.

DIAGNOSTICS

Base class package "%s" is empty.

base.pm was unable to require the base package, because it was not found in your path.

HISTORY

This module was introduced with Perl 5.004_04.

CAVEATS

Due to the limitations of the implementation, you must use base before you declare any of your own fields.
